Olivier Giroud inspired Chelsea to a thrilling win at Southampton and then targeted a top four finish

The win means Chelsea climbed to within seven points of the top four places with six matches left of the season – and Giroud insists they will do everything they can to secure Champions League qualification.

He said: “As long as it is mathematically possible we will believe we can reach the top four.

“We take the games one by one. We have got five or six finals to play after that we will see.”

Giroud has endured a frustrating time since leaving Arsenal in the pursuit of regular starts at Stamford Bridge in January.
